Passage 9.8.7
Θερσάνδρου δὲ τοῦ Πολυνείκους ἀνακαλεσαμένου σφᾶς ἐπὶ τὰ οἰκεῖα, τὰς πύλας διὰ ὧν τὴν κάθοδον ἐποιοῦντο ἀπὸ τῆς Ὁμόλης ὀνομάζουσιν Ὁμολωίδας. ἐρχομένῳ δὲ ἐκ Πλαταίας ἔσοδος ἐς τὰς Θήβας κατὰ πύλας ἐστὶν Ἠλέκτρας, καὶ ταύτῃ Καπανέα τὸν Ἱππόνου βιαιοτέρας ποιούμενον πρὸς τὸ τεῖχος τὰς προσβολὰς βληθῆναι κεραυνῷ λέγουσι.
When Thersander, Polyneices' son, recalled them to their homeland, the gates through which they made their descent from Homole were called the Homoloidian Gates. For someone coming from Plataea, the entrance into Thebes is through the Electran Gates; it was here, they say, that Capaneus, son of Hipponous, while making an especially fierce assault against the wall, was struck down by a thunderbolt.
